Sometimes breast cancer cells spread to the liver through the blood or lymph system. This is known as secondary breast cancer in the liver.
The cells that have spread to the liver are breast cancer cells. It’s not the same as having cancer that starts in the liver.
You may also hear this type of spread described as metastases, advanced breast cancer, secondary tumours, secondaries or stage 4 breast cancer.
When breast cancer spreads to the liver, it can be treated but cannot be cured. The purpose of treatment is to try to relieve symptoms and/or slow the growth of the cancer.

What does the liver do?
To understand some of the symptoms, it may help to know where the liver is and what it does.
The liver sits on the right side of your upper abdomen just under the ribs. It’s made up of different sections called lobes and surrounded by a capsule. It’s close to a number of other organs including the bowel, diaphragm (the muscle that separates the chest and abdomen) and right kidney.
The liver produces bile which helps digest food. It converts food into heat and energy, stores glucose and vitamins and breaks down harmful substances such as alcohol and drugs. It also produces important proteins including those that are needed to help the blood to clot. The liver is a large organ and can carry on working even if part of it is affected by secondary breast cancer.
Symptoms and how they can be managed
Symptoms of secondary breast cancer in the liver can range from mild to severe, depending on how much of the liver is affected by the cancer. Always report any new or persistent symptoms to your specialist.
Some people may have discomfort around the liver area only, while others may feel pain under their ribs or across their upper abdomen. This is because secondary breast cancer in the liver can cause the liver to become enlarged.
Sometimes you may feel pain in the right shoulder. This is called referred pain and is caused by the enlarged liver pressing on nerves that also go to the shoulder.
Most pain can be relieved or controlled. Always tell your doctors if you have pain. They’ll ask you to describe where the pain is, how it feels, how strong it is and what makes it better or worse. This will help them decide what to do to control your pain.
There are many different types of pain relief and often a combination of treatments may be needed. If your pain relief does not seem to be helping, tell your specialist as they can prescribe a different one. If your pain is not properly under control you can be referred to a specialist palliative care or symptom control team.

You may feel sick because the liver is enlarged and puts pressure on the stomach, or because toxins build up in the body from the liver not working properly. This can be treated with anti-sickness drugs.
It’s important for your doctor to try to find out what’s causing the nausea so they can prescribe the correct type of anti-sickness drug to control it.
Loss of appetite and weight loss
You may feel less hungry than usual and lose weight. This can be caused by the effect of the cancer or by the treatment. You might find it easier to eat little and often instead of having set meals.
Nutritional supplements may be useful if you’re finding it difficult to eat. Your GP (local doctor) or specialist can prescribe these or other medicines that may help. They may also refer you to a dietitian for advice.
Hiccups may be a result of the enlarged liver pressing on the diaphragm and causing it to spasm. It may help to sit upright and drink small amounts frequently. There are also medicines that may help.
Ascites is an excessive build-up of fluid in the abdomen. It can make your abdomen swollen and uncomfortable, and can sometimes make you feel breathless. Ascites can take weeks or months to develop.
A procedure called paracentesis may be used to relieve the symptoms. This is done by numbing the skin with a local anaesthetic and inserting a needle into the lower abdomen. Often this is done at the same time as an ultrasound examination.
A tube is then passed into the abdominal cavity, stitched into place or held in place by a dressing, and connected to a drainage bag outside your body. This allows the fluid to drain slowly over time, often over a few hours and sometimes over a few days. Occasionally the drain may need to stay in permanently.
Although you’ll be aware of the tube once it’s in place, it shouldn’t be uncomfortable. The tube will be removed once the fluid has stopped draining. This procedure can be repeated if the fluid builds up again. A diuretic (water tablet) is occasionally prescribed to slow down the build-up of fluid.
Tiredness and fatigue
Cancer-related fatigue is one of the most common symptoms experienced by people with secondary breast cancer. Everyone knows what it feels like to be tired sometimes, but cancer-related fatigue can feel much more severe.
It can come and go or be constant, and this can be distressing and frustrating. It has many causes, from psychological factors such as the stress of coping with the diagnosis, to physical ones such as the side effects of treatment or progression of the cancer.

You may become anaemic (a drop in the number of red blood cells) for a number of reasons, for example due to problems with blood clotting. A blood test can be done to find out if you’re anaemic and in some cases tablets may be prescribed or a blood transfusion can help.
Jaundice can occur when the bile duct (a tube coming out of the liver) becomes blocked or when the liver is seriously affected by the cancer.
If you develop jaundice the whites of your eyes and your skin take on a yellow tinge. In some cases your urine may become darker and your stools (faeces) may become pale.
You may need to have a stent (tube) inserted into the bile duct to drain the bile.
Jaundice can cause itching, which may be worse at night or when you’re hot. It’s important to keep your skin well moisturised. Try using a non-perfumed skin cream. Keeping this in the fridge can make it soothing when you apply it.
Sometimes medication may be prescribed to help relieve the itching and your specialist should be able to advise you about this. Sleeping tablets may help if the itching is stopping you sleep at night. Try to avoid alcohol, spicy food and heat (hot baths or direct sunlight), all of which can make the itching worse.
